Correct. Glide has a limited set of formatting options built into a date type column. If you want to go beyond that, then you need to us the format date column. It’s a type of computed column, so it doesn’t actually hold a value, thus you still need a regular column to hold the value.
However, I do agree that it would be nice if glide provided a lot more formatting options in the standard date type column.
I also wish that they had started with the basic components of Apps when they build Pages. I understand that the user interface is designed for different layouts and that each may have unique components for their purposes, but too many of the basics aren’t comparable between the two in name or functionality.
For a quick win, how about simply sorting the computed column list? Even after all this time, every time I create a Single Value column I find myself immediately scanning from the bottom of the list - it starts with S, so intuitively I expect it to be near the bottom
